Virgin Active South Africa Promo's are a hoax!!!

I recently joined Discovery Vitality and opened a Virgin Active premium membership. I qualified for the September Promo where you get a R1200 take-a-lot voucher or R750 Woolies voucher. The sales guy did not give me any terms and conditions of the promo but distinctively advised that I would only get the voucher once the first payment is made. At month end I went to my branch and made the payment, now I apparently no longer qualify for the voucher as there is an apparent terms & conditions clause that states the payment must be made via debit order. This is complete bull **** and the worst part is the sales guy and the call centre manager are too busy arguing about who needs to take responsibility of the matter and it's been a week since either one has gotten back to me! I WANT MY VOUCHER I AM ENTITLED TOO!!!!!!!!
